Chateau adds new, and updated registrations

Through a series of new registrations and expanded label updates, more growers across a variety of specialty crops will be able to use Chateau Herbicide to control their tough weeds next season.

Valent U.S.A. Corp.'s Chateau is now registered for use in alfalfa, asparagus, highbush blueberries, dry beans, garlic, pecans, hazelnuts, walnuts and numerous other tree nuts in California.

Now more growers can have that “take control” experience only Chateau offers with its broad spectrum, long-lasting residual control. The new registrations, many of which are supported by IR-4, join Chateau's already extensive list of registered crops, including grapes, stone and pome fruit, almonds, potato, mint, onions and Western cotton. In addition to the new crop uses, Chateau's rotational flexibility offers growers a broad range of plant-back choices.

“Growers have shared with Valent their need for a broad spectrum, pre-emergence herbicide that is flexible enough to adjust to evolving crop plans and needs,” said Kelli Woodwick, Chateau brand manager. “With these new Chateau registrations, now even more growers will have the flexibility they need in their herbicide program from a product proven to control even the toughest weeds.”

Chateau contains the active ingredient flumioxazin, a PPO inhibitor that binds to the soil and has low water solubility. Chateau stays where it is applied and will not leach or “lift off” by co-distillation or volatilization to harm crops in adjacent fields.

Chateau's low leaching potential makes it a great choice for long residual control of problem weeds in groundwater protection areas. Additionally, Chateau is formulated as a water dispersible granule and, therefore, VOC-free. Chateau requires at least one-quarter-inch of water for activation.

The pre-emerge herbicide is widely known for long-lasting broad spectrum control of more than 90 annual weeds, including tough-to-control weeds such as morningglories, nightshades, pigweeds, lambsquarters, mallow/cheeseweed, marestail, fleabane, smallflower morningglory, cutleaf eveningprimrose, swinecress, henbit, chickweed, and annual grasses.
